使用Chilkat库“预期的KEX_DH_GEX_GROUP/KEXDH_REPLY”错误

Question

我正在评估Chilkat SFTP的新图书馆。

但是，在连接到SFTP时，我得到了如下错误：

-Connect_SFtp --ChilkatLog

我主要是使用这4个函数连接到SFTP。

sftp.UnlockComponent(ChilkatKey);  
sftp.Connect(hostname, port);  
sftp.AuthenticatePw(username, password);  
sftp.InitializeSftp();  

我错过了什么？谢谢你的帮助。

正确的顺序应该和你的一样：

但是在这些人之后，您需要调用OpenDir和ReadDir(如果您需要获取文件，可以依赖远程文件夹)，比如；

string handler = sftp.OpenDir("remote_path");
SFtpDir compassDir = sftp.ReadDir(handler);

要下载一个不需要调用ReadDir但必须调用OpenDir的文件。在填充compassDir对象之后，您可以通过以下方法获得文件计数；

int fileAmount = compassDir.NumFilesAndDirs

或者你可以下载文件的名字如下；

sftp.DownloadFileByName("local_path","Remote_path_with_file_name");

很抱歉出错了……
